jExp

Simple XP/Rep Bar fitting roths UI and his oUF_D3Orbs. Mouseover the bar to view the tooltip. As long as your character hasn't reached the maximum level, the xp bar will be shown, after you've hit the maximum level, the rep bar will be shown. If you want to see the rep bar before you hit 70 (or 80 ;D), press and hold the control key.

Config
Open the jExp.lua file and edit the myscale variable, that's all.

i was wondering, theres a unitframeaddon called Pitbull, which has the option to add an anchored bar under your unitframe for things like EXP and REP, but it also has the option to show THREAT. is this an option you would concider to add to this addon? would be great if it was possible

I'm not getting a mouseover tooltip. Any tips on what I should do? I have it over a kgpanel which is Background framestrata. Looks like yours are on "Low", so this shouldn't be an issue.

Edit: I seem to have the bar too low on my screen - I have "Y" position set to 0, which must not be high enough to trigger the mouseover tooltip. Bumped it up a couple pixels and no go still. Bumped it way up (200) and it works. No idea what's going on. Maybe it's the framestrata.
